Chemical Bonds

Q. Here’s a fresh copy of lisdexamphetamine. When learning about acids and bases, we talked a bit about what makes particular parts of a molecular reactive. Shade this molecule by partial charge. That is, for atoms with a partial negative charge, shade them red. For atoms with a partial positive charge, shade them blue. For neutral atoms, shade them gray. Then on the molecule above, circle the bonds you think are most labile (i.e., reactive.) Explain your reasoning. What is the relationship between reactivity and charge?
